In a move to put public pressure on "sanctuary cities," the Department of Homeland Security on Monday published a list of 118 localities that have refused to cooperate with federal requests to detain undocumented immigrants.

President Trump ordered the department to publish a weekly list of all detention requests turned down by local jails, listing the agency, the undocumented immigrants and the charges they face. In an executive order he signed Jan. 25, Trump said the list is necessary to "better inform the public regarding the public safety threats associated with sanctuary jurisdictions."

Homeland Security Secretary John Kelly ordered Immigration and Customs Enforcement (ICE) to start producing the list last month, and on Monday, the agency issued its first public report.

It lists 206 cases in which undocumented immigrants were arrested on local charges and were set to be released from jails. ICE officials requested that the local authorities hold onto those people for up to 48 hours — a request known as a "detainer" — but the requests were denied.

The 206 denials took place the week of Jan. 28 to Feb. 3, although the arrests occurred as early as 2014.
